NOSE-PIECE FOR EYEGLASSES.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed December 11, 1905. Serial No. 291,290.

To all whom it may concern:

Be it known that I, GEQRGE BAUSCH, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Nose- Pieces for Eyeglasses, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates to improvements in nosepieces for eye-glasses inwhich opposite resilient leaves or springs are attached in any suitablemanner to the lens mounting so that the ends of the leaves are springpressed under comparatively light tension against opposite sides of thenose for the purpose of holding the glasses in operative positionindependently of the spring pressure of the bow which usually connectsthe parts of the lens mounting.

The essential purpose of my invention is to make the nose-piece as lightand resilient as may be consistent with durability so that the pressureupon the nose will not be excessive and at the same time to provideadjustable limiting stops to prevent excessive compression of thesprings beyond the limit of their resiliency.

A further object is to mount the springs in such relation to theirlimiting stops that the tension is gradually increased as the free endsof the springs approach said stops, thereby affording a comparativelywide range of effective action of the springs for different nose widthswithout necessitating the bending or adjustment of the bow.

In the practical use of spring-nose-pieces of this character, I havediscovered that when the springs are made sufficiently light to preventexcessive irritation of the nose, the tendency is to adjust the bow tosuch a degree as to bring all the gripping pressure upon thenose-springs and if the compression of these springs is not limited insome way, there is always more or 1(S'S liability of breaking thesprings owing to their extreme delicacy, and in my present invention, Ihave sought to avoid this undue strain and consequent breakage byproviding the mountings with adjustable limiting stops located in thepath of movement of the free ends of the springs so that when they arecompressed or spread apart in the act of placing the glasses upon thenose, the free ends of the nose pieces cannot be compressed beyond theirresilient power.

It is obvious that many different forms or styles of nose piecespossessing the desired resiliency may be employed depending somewhatupon the style of mounting to which the lenses are secured, but in allinstances, the active part of the nose piece is more or less rigidlyconnected at its lower end to a strap or other portion of the mountingwhile its other end expressure is comparatively light, but the tensiongradu- I ally increases as the upper ends are sprung from each otheruntil they engage their respective limiting stops, whereupon anytendency to spring the nose-pieces farther apart transfers the spring tothe bow, thus preventing any liability of straining the light nosesprings to the breaking point.

In the drawings,l have shown in Figure 1, a pair of eye-glasses equippedwith my improved nose-pieces. Fig. 2 is an enlarged sectional view takenon line 22, Fig. 1, showing in side elevation, the lens mounting andnose-piece. Fig. 3 is also an enlarged face view of one of thenose-pieces, showing a portion of the lens mounting to which the nosepiece is attached. Fig. 4 is an edge view, similar to Fig. 3, of thedetached nose-piece and mounting, showing the different positions inwhich the stop may be adjusted to limit the action of the springnose-piece.

In order to clearly demonstrate the practicability and utility of myinvention, I have shown a pair of eyeglasses 1- which are connected by'ahow 2 and suitable lens mountings or clamps 3- to which are secured apair of oppositely arranged nose-pieces 4. The novelty of my inventionlies more particularly in the construction ofthe nose-pieces 4- andtheir association with adjustable limiting stops 5 which are alsoattached to their respective lens mountings or clamps. The nose-pieces tand their limiting stops 5- together with the means for attaching themto their respective mountings are substantially identical and I will,therefore, describe one of such nose-pieces together with its limitingstop and manner of adjustment of said parts to the lens mounting.

The nose-piece 4 preferably consists of a comparatively light leaf ofthin spring metal arranged in a more or less upright position at aslight angle with the plane of the lens as best seen in Fig. 2, with itslower end integral with or otherwise united to the lower end of a strap6 provided with a laterally and upwardly projecting offset 7 secured bya screw S to the lens clamp or mounting 3, said screw 8 serving also toscrew the adjacent end of the bow -2- to the same mounting.

The united ends of the strap -6 and spring leaf 4extend some distancebelow the clamp or mounting 3 while the spring leaf or nose-piece 4extends from its junction with the strap -6 upwardly some distance abovethe mounting -3- and, therefore, has a resilient or spring actionthroughout its entire length from its junction with the strap 6 to itsupper end which is free to spring laterally through a considerable areas best seen in Figs. 3 and 4.

The strap 6 and lower portion of the spring leaf or nose-piece -4- liein substantially the same plane in the direction of movement of thespring leaf and normally diverge upwardly from their junction, theadjacent face of the strap 6being slightly convexed so that when thespring leaf -4- is pressed laterally,

it has a more or less rolling contact upon the strap 6 whereby thetension of the spring gradually increases as it is compressed or forcedfrom its normal position indicated by dotted lines in Fig. 3 and fulllines in Fig. 4. This gradually increasing tension of the spring undercompression from its junction upwardly is im portant from the fact thatthe pressure of the nosepiece upon the nose may be varied from anextremely light degree to a maximum tension, or pressure of the heavierbow spring 2, but the essential purpose in nose-pieces of acomparatively thin and light spring leaf is to' relieve the excessivepressure upon and irri tation of the nose and still have suflicientgripping power to hold the glasses in operative position. The spring is,therefore, pxtremely delicate and in order to avoid any possibility ofbreakage, I have provided the limiting stops -5 which are, in thisinstance, made of light bendable metal preferably integral with thestrap 6, although it is evident that it may be made from a separatepiece of metal and attached to the lens mounting in any other mannerthan that shown. In fact, I have shown the spring leaf or nosepiece -4-,stop 5-, strap 6 and its offset 7 as formed from one or the same piece,but only for the convenience of illustration of the principle of myinvention as it is clearly obvious that each of these elements may be'made separately and secured together in any well known manner withoutdeparting from the spirit of this invention.

The limiting stop 5 is located between the lower and upper ends and justat the outside of the spring leaf4-preferably nearer the top of saidleaf and is adapted to be bent to different positions as best seen inFig. 4, so as to throw the abutting face of the stop nearer to, orfarther from, the normal position of the leaf 4, thereby allowing theleaf to spring laterally a greater or less distance as may be necessaryor advisable to avoid any liability of breaking or unduly straining saidleaf while under compression or tension.

The spring leaf 4 is normally set or adjusted so that its free upper endwill normally spring inwardly from its junction with the strap --6 undergradually increasing tension from the junction upward so that when theeye-glasses are placed upon the nose, the upper ends of the leaves4-willengage the opposite sides of the nose under an extremely light pressureto avoid, as far as practicable, excessive irritation, and that thespaces normally intervening between the upper ends of the leaves andtheir respective limiting stops allow a considerable range of action ofthe nosepiece for different nose Widths without adjusting the spring bow2', thereby avoiding excessive irritating pressure of the latter whichis necessarily heavy and less resilient than the spring leaves 4.. If,however, by careless adjustment of the spring bow or carelessmanipulation of the delicate leaf springs4, the latter should be spreadapart or brought under excessive tension beyond their resiliency, thelimiting stops 5 which are adjusted to prevent excessive tensioning ofthe spring-leaves would engage and limit their lateral compression,thereby avoiding any liability of breakage of said leaves, and at thesame time, transferring the tension from said leaves through the stops 5to the heavier spring bow 2. This latter effect would soon indicate tothe wearer the necessity for proper adjustment of thebow to throw theleaves farther apart or, at least, a sufficient distance apart so thatthe pressure upon the nose would be entirely within the tension of thespring leaves&-.

The salient feature of my invention is to provide a pair ofcomparatively light spring leaves acting independently of the bow togrip the sides of the nose under a less irritating pressure than wouldbe produced by the tension of the bow spring and at the same time toprovide adjustable abutments or stops in the paths of the free ends ofthe leaves to prevent excessive cornpression or lateral springing of theleaves to the point of breakage.

What I claim is:

1. In a lens-mounting for eye-glasses, a pair of nosepieces eachconsisting of two upright strips of metal united at their lower ends anddiverging upwardly from each other, the inner strip being springtempered and the outer strip having its upper end bendable toward andfrom the spring tempered strip forming an adjustable stop therefor tolimit the outward spring of the spring-tempered strip.

2. In a lens-mounting for eye-glasses, a pair of lens clamps, straps ofbendable metal having lateral offsets secured to the'clamps, said strapshaving upright portions extending above and beneath their respectivelateral offsets, spring-leaves united at their lower ends to the lowerends of their respective straps and extending upwardly above the upperends of said straps, the upper extremities of the straps being bendabletoward and from the springs to form limiting stops therefor.

3. In combination with the lens clamps of a pair of eye glasses, uprightstraps secured to said clamps, spring nose pieces having their lowerends united to the lower ends of the straps and their upper endsextending some distance above the upper ends of said straps, each strapand its nose-piece diverging upwardly from their lower ends, the upperend of each strap being bendable to throw its extremity nearer to orfarther from the nosepiece.

i, In a lens-mounting for eye-glasses, two opposite pairs of metalstrips, those of each pair being united at their lower ends anddiverging upwardly, the inner strip being formed of spring metal andconstituting a nose-piece, and the outer strip having its upper endbendable to throw its extremity nearer to, or further from thenose-piece.

In witness whereof I have hereunto set my hand this 5th day of December,1905.
